Good pack

i've used it for schools and a day hikes in Hawaii. The built in rain cover was great as was the net section to allow wet things to be stored instead of tied on.

The twin side nets are great for city use to cary water bottles.

I doubt I could have come up with a better design.

All around a much used pack and with the fact of 911 it resides in my vehicles at all other times.

I use this hydration pack for mountain biking and am quite pleased with it. It fits my "kit" perfectly when not in use and compresses and stabilizes the load when on the trail. My knee pads and helmet stuffed in the one side and center net pockets when not in use, and the other side net pocket keeps my pump and a spare tube. The smaller compartment has two handy pockets perfect for cellphone and wallet. Main compartment holds plenty. Good pack.
